定語從句
1.定義：用來修飾名詞或代詞的從句
例如：She is a beautiful girl （who teaches English.）
先行詞 關系詞（定語從句）
2.關系詞作用：連接作用：連接先行詞和從句
代替先行詞：在句子中充當成分
限制性定語從句關系詞
先行詞 關系代詞 關系副詞
主語 賓語 表語 定語 狀語

物 That或which That或which或不填
注意：whose+n.=the+n.+of which/of whom
= of which/of whom+ the+n.
例如：They came to a house whose back wall had broken down.
= They came to a house the back wall of which had broken down.
= They came to a house of which the back wall had broken down

A.where B.who C.that （which/不填 ） D.whom
關系副詞（不缺少成分）
先行詞是time, day, morning, night, week, year 等,用關系副詞when
注意：當occasion 表示“特定的時刻”，用關系副詞when
例如：Do you know the date when Lincoln was born
先行詞是place，spot，street，room，city等用關系副詞where
注意：當point，situation，case，condition，stage（階段）等表達“情況，境地，場合”等抽象意義的地點時，用where
例如： This is the hotel where they are staying
先行詞是reason，用why
例如：That is the reason why he is leaving so soon.
4.鞏固提升
Today, we’ll discuss a number of cases ____where_________ beginners of English fail to use the language properly.
注意事項：a.關系副詞（where/when/why）=介詞+which
介詞后只能用which；介詞根據先行詞或動詞搭配來選擇
例如：I was in Beijing that day when(=on which) he arrived.
The office where(=in/at which) he works is on the third floor.
This is the chief reason why(=for which) we did it.
b.當先行詞表時間的time，day等和表地點的place，house等時，一定要注意分析關系詞所在句子中所充當?shù)某煞帧?br/>例如：I‘ll never forget the day ____when_______ my hometown was liberated.
I‘ll never forget the days__that/which/不填_________ we spent together last summer.
His father works in a factory ____where__________ radio parts are made.
His father works in a factory _____that/which_________ makes radio parts.
c. when和where既可引導限制性定語從句又可以引導非限制性定語從句，why只能引導限制性定語從句
非限制性定語從句：與主句關系不密切，附加說明，用“，”分開
例如：Hismother，whom he loved deeply, died ten years ago.
非限制性定語從句關系詞
先行詞 關系副詞
主語 賓語 定語 狀語
人 who who或whom Whose When Where
物 which which
其先行詞可以是名詞，代詞還可以是整個句子（關系詞可用as/which）
關系詞特殊用法：
That 與which，who, whom用法區(qū)別
情況 用法說明 例句
只用that的情況 先行詞為不定代詞all,everything,anything,nothing,little,much 先行詞被不定代詞all,any,every,each,much,little,no,some,few修飾時 先行詞被形容詞最高級和序數(shù)詞修飾時 先行詞指物且被the only,the very 修飾時 先行詞既指人又指物 句子中已有who或which，避免重復 He told me everything that he knew.
只用which，who, whom的情況 在非限制性定語從句中，指代物只能用which，指人用who/whom 在由“介詞+關系詞”引導定語從句中，只能用which指物，whom指人 先行詞本身時that/those,指物時用關系詞which，先行詞為those/one/he,指人時，多用who 1)He has a son, who has gone abroad for further study. 2)I like the person to whom the teacher is talking. 3)That which I say and do is my own affair.
2.as 與which區(qū)別
定語從句 區(qū)別 例句
限制性定語從句 名詞前有so,such.as,the same修飾時，關系代詞用as He is not such a fool as he looks.
非限制性定語從句 都可以指代前面整個主句。 As有正如的含義；放在主句前或后都可以，which有這的含義，只能放主句后
3.先行詞是the way,意為方式方法，且關系詞在句中作狀語時，關系詞為that/in which/不填
鞏固提升
They wouldn’t agree to sell the house to us at the same price ______as_______ they had promised,___which______ was rather disappointing.
